SPOOL-HOLDER.

Application filed July 26, 1913. Serial No. 781,296.

To all whom it may concern:

Be it known that I, MAXIMILIAN J. OTTO, a citizen of the United States,residing in the borough of Manhattan, city, county, and State of NewYork, have invented a new and useful Improvement in Spool- Holders, ofwhich the following is a description. 3

This invention relates to spool-holders and particularly tospool-holders adapted to be applied to sewing-machines.

Among the objects of my invention may be noted the following: to providemeans, for holding a spool upon the arm of a sewing-machine, which maybe readily removed and quickly applied, and which may be applied to anytype of sewing-machine now known to me; to provide a spool-holder forsewing-machines for holding spools of thread'thereon in position forsupplying thread to the needle or other executive element of themachine, and by means of which the thread may be freely paid off fromthe spool without fear of entanglement with the spool or spool-holdingmeans; to provide a simple, cheap and effective spool-holding devicehaving frictional means for holding it to the ordinary spoolspindle, orsimilar support, of the machine, and capable of being raised and loweredon said spindle, or adjusted, or r0- tated thereon for purposespresently described; to provide a spool-holder made of a single piece ofresilient material; and to provide a spool-holder which may be adaptedto or substituted for the ordinary spo0lholder now found on domestic andmanu- .facturing machines.

With the above objects in view and others which will be detailed duringthe course of this description, my invention consists in the parts,features and elements, and combinations thereof hereinafter describedand claimed.

In order that my invention may be clearly understood, I have provideddrawings wherein: Figure 1 is a side elevation of a portion of asewing-machine showingthe application of my invention; Flg. 2 1s aperspective view of my spool-holder; Fig. 3 is a top-plan view showingmy spoolholder in place on a portion of the machine, the spool beingshown in dotted outline; and Fig. 4 is a view similar to Fig. 3 butshowing the parts in a different position.

Referring to the drawings, it will be seen Specification of LettersPatent.

.to be adjusted on the spindle Patented Apr. 27, 1915.

that my spool-holder, in the form which I' have chosen to illustrate forthe purposes of this application, consists of a single piece ofmaterial. Preferably, I form the spoolholder from resilient wirecapable, when bent into the form of my invention, of applying frictionto the spindle or pin to which it is adapted.

Referring to Figs. 1 and 2, it will be seen that my spool-holderconsists of a securing portion and a spool-holding portion. securingportion comprises a loop or eye 1 formed at one end of the wire andadapted to slide freely over the spindle 2, usually extending verticallyfrom the sewing-machine arm 3. eye which isbent obliquely upward andsubstantially reversely to form the V-shaped resilient or spring tongue5 located midway, or substantially so, between the eye 1 The A portionat extends from the 7 and a similar oppositely disposed eye 6,

her 7 of the securing portion. Beyond the eye 6, the wire is extended atan angle as at 8, and then at a right-angle as at 9, to form thespoohholding portion, and then eXtend ed parallel with the member 8, toform the spool-holding pin the spool-holding pin 10'and the securingportion is sufficient to afford space for the largest spool that may beused on any sewingmachine, domestic or manufacturing.

In the several figures it will be seen that the two eyes 1 and 6 arearranged in alinement, or so that they have the same, or substantiallythe same, center. It will also be seen that the spring-tongue isarranged be tween the two eyes and directly in line, or substantiallyso, with the centers thereof, so as to press with considerable force orfriction upon the spindle 2, to which the holder is applied. Thus, whenthe securing portion is slipped down over the spindle 2, the latterpasses through both the eyes 1 and 6, and the tongue, between the twoeyes, frictionally engages the said spindle. The friction between thetongue and the spindle retains the spool-holder firmly upon the spindle,but permits its easy removal and rotation on the spindle. The frictionalhold of the tongue also permits the spool-holder so as to locate thefree end of the spool-holding pin 10 as far as may be desired from thebase of thespool or the arm'2 of the, machine; but, it' should 7 Irangement of the pinlO is" such that its free end will be a distanceabove'the base, or eye {-1, of the securing portion of theflspoolholder;Thus' when the spool is set upon' V the machine arm w'ith the spindle 10extend the arm', from becoming ing into the axial passagethereof,thespoolwill be so held as to prevent the thread, shoulditrfreely' unwind and become loose aboutfthe bottom of the knotted,entangled,

' or otherwise impededlinits free passageto the executive elements'of 4the machine. a Toapply a spool to the holder, it is only necessary,after having placed the holder in position 'asshown'in Fig. 1, to rotatethe holder up'on'the'spindle .2 until the spoolholding pin 10 is beyondthe machine-arm sufficiently far to permit the spool 11 to be slidthereon, as shown in Fig. 4. Then the V spool-holderis rotated, bypressure upon the spool, back tojthe position shown in Figs. 1 and 8, sothat thespool mayjrest on the machine-arm; It will alsobeunderstood 1that a fresh spoolof thread may be quickly which event a spindle,

,applied and that anysize spool can be accommodated. r

In some instances the spool-spindle 2, found on a manufacturing machine,may "not" be' adapted to receive my holder, in such as 2, may besubstituted for such special spool-spindle.

Having thus described my invention, what I claim and desire to secure byLetters Patcut is: r i 7 1.
